[Live-demo] please avoid chown user:user

[Stefan Hansen]

Hi all!

I played in the last couple of days a bit with generating an ISO-image
from the VM and ran into a few problems.

One of them is that some install-scripts change the owner of some files
outside $HOME to "user". Unfortunately this doesn't go well when you
boot from the LiveDVD. The original "user" is deleted, when the ISO is
generated, and a new user is created during the boot process (apparently
that is the way things have to be). Files that belonged to the old
"user" belong on the LiveDVD to the uid=1000, but the new user has the
uid=999. Therefore, the new user cannot write these files and some
applications won't work (so far I had problems with Geoserver and
Degree, but I haven't tested all applications). So Instead  of changing
the owner of a file or directory, please keep root as owner and just
change the access permissions. If you do so, please only change the
write-permissions of a file only if you really, really have to. AFAIK
everything writable is loaded into the memory, when you boot from the DVD.

cheers,
stefan
